Observation metrics for periodic events
A Python package to compute and visualize observation metrics for periodic events.
In Astronomy, portrait is useful to answer the following questions:
- How much of an orbit with period
$P$ has been observed given certain observation times? (tutorial) - What period
$P$ matches with this list of events? (tutorial) - How a certain target must be observed to cover all orbits with periods lower than
$P$ days?

Given the range of periods you want to cover, here is how to compute the amout of phase covered by your observation times
from portrait import coverage
time = ... # your observation times
periods = np.linspace(0.1, 10, 2000)
covered = coverage(times)(periods) And plotting it with matplotlib
import matplotlib.pyplot as plt
plt.subplot(111, xlabel="periods", ylabel="coverage")
plt.plot(periods, covered, c="0.5")
pip install portrait
